Where can spasmodic Google Search traffic come from on Youtube?

Question

Google

Good afternoon!
There is a YouTube channel with ~50 thousand subscribers.
A strange story began in January - massive Google Search traffic began to come to some new videos.
The peak fell on new videos, within the first 48 hours after publication. Then a sharp drop and a complete zero. In April, this story began for almost every video: - this is a graph
only for Google Search for the last 90 days
, we are seeing a drop in impressions.
It looks like a black cheat (of course, we don’t spin anything ourselves), but when cheating, left-wing sites, other countries usually come out ... and here Google Search and Russia + CIS (in the same proportions as through other channels).
YouTube support, of course, says that everything is OK, this is how your channel develops.

Has anyone had a similar situation? How did you deal with her?

Are there any opportunities, at least at the moment when the traffic is dropping, to see what requests and where it shines at all? If we assume that this is not cheating, the only thing that comes to mind is getting into some ultra-high-frequency requests and then leaving them due to weak (for ultra-high) behavioral search results.

Answer 1

not the left, Google tests the subject and audience in this way ; the
conclusions, alas, can also be tough) so just increase the number of subscribers
